To all ywho/1i t may concern:

Be it known that I, Cricri. HAMELIN TAY- LOR, a citizenl of the United States, residing at Detroit, county of lVa-yne, NState of Michigan, have invented a certain new and useful Iinprovenjient in Internalfombustion'Engines, and declare the followin to be a full,

clear, andiexact description of t e same,such' as; will enableothers skilled in the art to which it pertains to make and use the sanity reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to internal combustion engines and an object of my improvement is to provide for a. construction that shall facilitate assembly ot' the parts and obviate danger of leakage.

I secure this object. in the device illustrated in the accompanying drawing in which:

Figure 1 is a sectional elevation of the upper part of anengine embodying uiy invention.

Fig. 2 is a partial -plan view of the saine.- .F ig. 3 is adetail sectional elevation, the

parts `loeing separated. A

Fig. 4 is a View similar to Fig.f3 showing a modified construction.

(L is the crank case which is extended upward in a cylindrical` 'arta which forms the iiiclos'ing wall of te lower part of V`the water jacket. (1i5 is an inwardly extending annular flange at the top of the water jacket.

).is.tlie cylinder which l inake of a single piece of steel having its upper end closedV `nular flange at the upper part of the cylindrical portion (1.2 which extends from the crank case (1.. The upper surface of the tlaiige (1.3 is machined to coact in forming a tight joint.

bt b2 are valve ports through the upper end ot the cylinder the axes et' which diverge outwardly. There is a conical seat b specification f Letters raient. Application filed May 6, 1253.8. ,Serial No. l.

formed around the outer end of each of the valve ports b2.

(i is anfalinninuin casting containin the valve-passages c2102 which extend horizon-jv tally inward and then bend downward at c3 toward a' vertical direction. There are passages ci formed in the casting c to constitute a water jacket.V aro-iind the walls of the valve-passages c2 c3. c5 is a downwardly ex! tending cylindrical portion of the casting (i Aterminating at its lower en d in an outwardly extending annularl flaiwe c3 which is machined lon its underr sur ace.' l

b5 is an annular flange extending outward troni the upper portion of the vcylinder integral therewith, and having its upper and lower faces machined.

The flange?)5 rests upon the flange. a? and the flange .(26 rests upon the flange b5 and the three flanges are secured 'together vby` -bolts c to form a tight joint and to uiite-v the cylinder b, crank case (1.2 and casting o together. s Y

There l is a conical bearing of formed l'around th'ejopen lower end of each of the parts @3.0i3 the valve-passages c2 o3.' The se i' walls surrounding the opening from each of I the parts. (f3 rrthe valve passages is axially .8x5

in line with the wall of the opening at the upper end of the adjacent valve passage b2.'

c is a water jacket inclosed between the cylindrical dertien o5 of the casting (i and' the upper -eind of the cylinder b.

( is a .rin'gof soft metal'having conical passage caf and the conical wall around the adjacent .opeiiing from the port b2.,

, In assembling the thin steel cylinder 'b is placed within'the cylindrical portion a2 oit` the crank case (L with thev flange resting upon the packing material a: which is between it and the flange (L5 extending inwardly from the crank case. The rings (l' are then placed upon the conical surface of the walls around the outer ends of the ports '62. rl`he -astiii with theconical wal-l (f4 resting upon the upper conical portions of the outer walls of the rings (Z. Thisbrings the flange 06 in position` to be secured to the fla-nge a3.'

-The bolts (f7 are inserted andscrewjed to c is then adjusted to place 'oexteiior 'walls (l2 adapted to tit against the l conical' walls around the opening from the )lace claniiinoi the Han'es (La b5 and d I P1 E. 9

firiiily together and drawing the casting o downward thus compressing the rings d d and t'orining a tight joint between the walls through a' bolt hole at the center of the castingI c and engaginga screw-threaded opening in the upper end of the cylinder The i pasting c is formed at its center and lower face to constitute an engaging surface that .may be inachinedand the upper end of the cylinder b is provided with 'a corresponding engaging surface and there is a shim e placed between said surfaces.

Instead of' he smooth conical .seats b3 and b4 stepped, or annularly indented sheets maybe used as shown in Fig. l at b and 043;. In this case a conical ring of thin'metal al would be used which would he interposed between the stepped portion (mand 53a and Awhen the 'casting c is screwed to place the ridges of the surfaces 53a and c4u are forced against the ring da indenting said ring in annular c orrugations and forining a tight joint in this way.

The `joint secured by the bolt of' being inl approximately ythe plane of the rings. the engaging position of the parts will be ixed and not variable due to the extension and contraction of the material.

lso

ing position 0f the other surfaces fvliicli` easing to their engaged position.

' The conical form. of the engaging ring allows a considerable margin for the motionl of the parts so that the joint formed by the ring and its engaging surfaces will beA tight without an over refinement as to the engagarts.

What I claim is:

1,. nian internal combustion engine, the cou'ilifination ci a 'cylinder having its end closed, a valve port extending through said determipse the relative pgsition of these enend with its axis divergine outward from` the axis ofthe cylinder, said port being provided With lan engaging surface around its outer end in a plane at right angles to the axis of the cylinder, a separate (piece having avalve passage therein adapte to form an extension of said port and having anengaging' surface around its inner end parallel to said engaging 'surface of the port, a compressible ring between the walls at the ends ofsaid passage and port, and means for ses curing said separate piece to said cylinder that shall cause the relative engaging movement of said piece and said cylinder to `loe parallel to the axis of said cylinder.

2. In'an internal combustion engine, the combination of a cylinder having its 4end closed, a valve port extending through saidend with its axis diverging outward from the axis of the cylinder, 'said port being provided with a conical engaging surface around its outer end in a plane at right angles to the axis of the cylinder, a separate piece having a valve passage therein adapted to form an extension of said port and having a conical engaging. surface around its inner endparallel to said engaging surface-of the port, a compressible ring having conical sur- ,faces 'adapted to engage against the conical engaging 'surfaces of said port and passage, and means foi-.securing said separate piece to said cylinder that shall cause the relative engaging movement of said piece and said cylinder to be parallel to the axis of said cylinder and shall limit the extent of said movement.

3. In an internal,combustion engine, the combination of a cylinder having its end closed, a valve portextending through said end 'with its axis diverging outward froml the axis of the cylinder, said port being provided withan engaging surface around its llimit the extent of said movement, said engaging surfaces heilig annularly corrugated.

In testimony whereof I sign this specication.
